However • It wasn’t very flexible: building new features would often require the addition of fields and associations which would cause response sizes to grow everywhere even though they weren’t used everywhere. • Caching of whole objects would sometimes cause requests to spend more time fetching the cache than building the response from scratch. This is partly due to our serialization library’s caching strategy of fetching individual objects rather than batching The backend team sought to try out GraphQL as an alternative to give clients just what they needed. Brian will present a summary of how he went about developing a GraphQL API and his learnings along the way. Bio: Bio: Brian Underwood is a Platform Engineer at Fishbrain. In previous lives he has been a full-stack Rails engineer, a developer advocate for Neo4j, and a researcher of text analytics solutions.

    17.30 - 18.00 Doors open, food and drinks served, mingle. 18:00 - 19:00 The Agile Testing Principles by Sofia Hedlund and Heidi Nummi Abstract: How do we make sure to maintain high quality in our products? Who are responsible to make this happen? Why should we lift the burden of quality of the lonesome tester's shoulders and start to collaborate? The Agile Testing Principles, created and presented by Sofia Hedlund and Heidi Nummi, are just what it says; some basic easily understood agile principles not telling us what to do but rather inspire us to find out our own way. Or as Ralph W Emerson said "If you learn only methods, you'll be tied to your methods. But if you learn principles, you can devise your own methods." This prone approach will even make that old dusty testing strategy document completely obsolete. Bio: - Sofia Hedlund Experienced strategist and change management consultant certified in Agile Leadership, Scrum, SAFe and Quality Assurance. Likes all things Agile and knows how important it is to start with an organisation's culture. Great facilitator and workshop leader. - Heidi Nummi Agile spokesperson and growth catalyst, with thorough experience within testing methodologies. Techie with interest in both product and team development. Has a mission to get management to understand and support agile leadership. 19:00- 19:10 Break 19:10 - 20:10 SOLID – The five commandments of good software by Chris Klug Abstract: The SOLID principles. The five commandments of the software world. Forgotten for years, as developers focused on JavaScript frameworks with stupid names and complicated patterns. Not grasping that the SOLID principles transcend beyond frameworks and patterns. The SOLID principles are the foundation of building good software. They are the breakers of monoliths. The decouplers of coupling. The squashers of regression bugs. One might even say that they are the creators of maintainable code. Unless you already a believer, you need to attend this session and get on the right path. Chris, the bringer of SOLID knowledge, will go through each one of the principles, explaining what it means, what it will do for you, and why you should stop breaking it. You will even be shown C# code that explains how they help you, and what problems will haunt you if you ignore them and are faced with their wrath. Bio: Chris Klug is a developer-badass-as-a-service that either creates or solves problems depending on who you ask. He loves creating and building things. Whether it be a new application, a new kitchen or a new RC helicopter, you will see him building things all the time. Most of the time, that means writing code and solving problems for clients at a company called tretton37 in Stockholm though. Except for the many days he spends at conferences and user groups, talking about doing things he is passionate about, and for the days he goes mountain biking, IPSC shooting, kiteboarding or RC helicopter flying.

    Agenda: 17:30 - Doors open. Light food and drinks will be served. 17:45 - GDG exercise 18:00 - Presentations starts 1) 18:00 - 19:10 "Build Microservices with Google Cloud Pub/SubDescription" by Abdelfettah Sghiouar from Google Abstract In the Era of cloud, the rage for Microservice architecture is on. A lot of people are migrating (or planning to migrate) to it, but this architecture is little to unknown to many people. Various solutions exist on the market and they all do more or less the same thing, but the questions is where to start from ? which solution to pick ? Managed or Un-managed ?In this talk we will explore Google Cloud Pub/Sub, a highly available, infinitely scalable, low latency messaging system built for Cloud, we will look at the concepts of Cloud Pub/Sub and use it to build a Microservice architecture. Bio SGHIOUAR Abdellfetah (Abdel for short) is a Google Strategic Cloud Engineer, he works with customers helping them achieve success on there journey to the Cloud. with 10+ years of experience, from Google Datacenters to startups, from product development to DevOps and operations, he has a deep understanding of the challenges that companies of all sizes face everyday with their product. 2) 19:15 - 20:00 "Achieving Business Agility by Agile Architecture" by Mina Boström Nakicenovic from NetEnt Abstract: Once upon a time few believed that big up-front design methodologies, like Model-Driven Development (MDD), could be used in agile software development due to their complexity and long starting curve. This story describes how we successfully reduced the complexity of the MDD concept, by applying agile principles and lean startup methodology. We managed to produce a working MDD solution, which created business value within a short time-frame. Such an agile MDD architectural solution, although being a “worse” solution compared to a technically perfect one, was in fact a better solution since it delivered business value. And this was not the end - the story continues. We used our MDD architecture to build an internally developed computer virus - but a well-intentioned one! We applied the “minimum viable solution” concept when developing it. The mentioned virus spreads across the whole system and does a lot of useful things. Curious to know more? Welcome to my talk! This talk will provoke you to think about a well-known question “Is Worse Better?” It demonstrates “how worse can be better” if the focus is on delivering a business value. Bio: Mina works as Head of NEL Development at NetEnt. She has 20+ years of experience in software development. For many years Mina worked as an architect who wrote code. She is passionate about agile software development and her main focus is on delivering business value through optimal architectural solutions. Mina is a regular speaker on European software development conferences. Her passion for software development has spread within her family. She and her husband are often taking their 3 kids to conferences, where they are coding together and presenting together, as an agile family. In 2016 Mina was awarded 3rd place on Sweden’s TechWorld best developer list.

Meet & Greet 18:00 - Presentations starts 1) 18:00 - 18:45 "The Front is the New Back" by Ado Kukic a Developer Evangelist at Auth0 Twitter: https://twitter.com/kukicado Github: https://github.com/kukicado "In the last couple of years, we have seen a significant shift in the way we write apps. More and more, logic is being pushed to the client (browser, native apps, IoT) and new services have emerged to reduce even more the need of backends. But there's more to come. What if we don't need ANY server at all? What if we could write apps mixing client and server side code without having to worry how that code runs? In this session we will go over a new way of writing completely backendless applications using Webtask, Token-based Security, and Angular." 2)[masked] – Break with something to eat and drink 3)[masked] "Sprylang and Odd Ideas in Language Design" By Göran Krampe, author of the programming language Spry and team lead at Evothings Labs AB. http://sprylang.org (http://sprylang.org/) "Implementing your own programming language opens up opportunities to experiment in directions that may be fun, clever or downright idiotic. When designing Spry, which is still evolving, I am trying to find new ways to do things - even for the most established mechanisms. Obviously, because it's interesting and fun, but also because most programming languages are stuck in the-way-it-has-always-been-done-must-be-best. In this presentation I will show some of these ideas in Spry, what they were inspired from and hopefully open up a dialog about the need for language evolution and broadening of our views on how a programming language must work." Feel free to contact with me if you have any question. Thanks and Cheers, Sevil

How can you use the tools they're giving back to the community?" 2) 19:00 - 19:45 "Prototype your idea today!" by Jonathan Trujillo "Product managers want to materialize ideas rapidly and test their hypotheses. On the other hand, designers and engineers don't like to build something that will be thrown away. Seriously, who would? Prototyping should be a low commitment effort. For the Klarna Payments Direct Debit launch, we came up with a pretty nice setup to swiftly build high-fidelity prototypes using Sagui, the Klarna UI and some more React. In this session I'll show you how to build your own cool prototypes, and tell you why you should do it more often." 3) 19:45 - 21:00 Whoop whoop - Mingle time at Klarna office.
